保溫水瓶旅行版

I took this on a long hike and the 500 ml size fit perfectly in my backpack side pocket. 24 hours later there was still ice in it, which shocked me honestly. The stainless steel body feels really solid too.

Took it on a 6-hour train ride and the tea was still steaming when I got off. The 500 ml size fits perfectly in my backpack's side pocket, and the stainless steel keeps everything tasting clean, not metallic.

I was worried it might leak in my bag, but the seal is solid even when I toss it sideways. My tea was still pleasantly warm after a full eight-hour work shift, which is exactly what I needed.
